Following Shalev suggestion, I compared the number of particles(it can include protons and neutrons, becasue this check was done prior the Veto modification) in HAND for Carbon and for LD2 runs.
after estimation of the number of particles in the peak and normalizing to the target size-density-charge I got ratio C/LD2 ~ 4 +- 1
We currently replaying all runs after the change in order to have better estimation.
